Which treatment is NOT included in the practice of waxing?

Electrolysis is a method of hair removal that involves using an electric current to destroy the hair follicle, making it a form of permanent hair removal rather than waxing. Waxing, on the other hand, is a temporary method of hair removal that either removes hair from the root (epilation) or from the surface of the skin (depilation).

In the context of waxing, both depilation and epilation refer to techniques that remove hair but do so through different methods. Depilation involves cutting hair at the skin's surface, while epilation involves pulling hair out from the root, which is precisely what waxing does.

Threading is another hair removal technique that also is temporary and focuses on twisting a thread to pluck hair from the follicle, making it related to the practice of waxing.

Therefore, electrolysis stands apart from these methods, as it is not a waxing technique and falls under a different category of hair removal practices. Its distinction lies in the fact that waxing provides temporary results while electrolysis aims for permanent hair removal.
